Be it known that we, EDWARD A. GanvEY and CHRs-'rornsn A. GARVY,citizens of the United States of America, 'residing inthe city ofSin-Louis and State of Missouri, have in' vented certain new and usefulIrnpro vements` .in Shocl -Absorbers for Vehicles, of which thefollowing is a full, clear, and exact-description, reference' being hadto the accompanying drawings, forming part' of this specification.

.Our invention relates to means in-ave,

26 is a holder preferably ofchannel shape in which the bolster isclamped and which is detachably fitted to the carrier 24 tobe sup ported-by vsaidcarrier in a position 'to cause the bolster in said holder toextend transversely-[across the vehicle and haveits end permit the mtro-'portionsinclosed within the saddles 1 9 so as topermit' of the shoes'of said saddles resting upon the tops of said end portions.v` Thebolster holder is detachably mounted in the carrier 24 to ermit of itsbeing withdrawn from the carrier in the event of the bolster secured tothe holder becoming injured in service, or becominfr in any other wayunfit for further use. Fe thus provide for the separation of a bolsterfrom the vehicle and the introduction of another bolster fitted to aholder being inserted into the carrier 24 to take the place of the onepreviously in use und this operation of replacing one bolster by anotheris easily and speedily accomplished. Thebolster may be secured to theholder by clenching it therein in a manner common to that in whichpneumatic tires are commonly secured to vehicle wheels or in any othersuitable manner. Vfe provide, in one end of the bolster holder, whichpreferably extends beyond an end of the carrier 24, a han dhole 127, seeFig. V, in order that the holder may be readily grasped in inserting andwithdrawing it from the carrier 24 and we also preferably provide keyholes in the carrier and holder adapted to receive a key 28, that servesto retain the bolster holder within the carrier when it is in placetherein.

The herein described construction of a bolster carrier and bolsterholder in which the latter is detachably fitted to the former so that itmay be readily inserted and withdrawn therefrom, as illustrated in Fig.11, is a most important one in that it provides for the substitution ofone bolster for another with ease and speed, thereby avoiding theirksome and tedious operation of 'replacing pneumatic tires upon motorvehicle wheels, which tires are, in accordance with our improvements,intended to be supplanted by the bolsters herein described.

In'the practical use of our shock absorber the force of a blow upon aground wheel of the vehicle is transmitted from the wheel to the axlemounted therein-from said axle to the radial bar 4 and its extension 5and the bolster carrier mounted upon a pair of radial arm extensions.care of by the pneumatic bolster so that it is not forcibly transferredto the body of the vehicle, this being due to the body of the vehiclebeing supported upon the bolster through the medium of the springr 9 andthe saddle 19 connected to said spring and resting upon the bolster.

1t is to be .understood that there is a bolster 25at each end of thevehicle, a pair of the main springs 9 at cach end of the vehicle, at thesides thereof and four of the saddles -19 associated with the springsand supported by the holsters. The saddles 1t) are connected by bridgepieces 19, see Figs'. lll and V, at each end of the vehicle which serveas stays between these saddles, and the bridge pieces are preferablypivoted to the saddles in order that the saddles may play at each sideof the vehicle to a limited degree in the event of one This shock isthen takenl or the other of them at the end of the vehicle being` actedupon more forcibly than the mating saddle.

1n Figs. YU and Ylll. we have shown a modification in which the bolstercarriers 24 are mounted upon the axle of a vehicle to extendtransversely of said axle beneath the main sprinvs 9 thatare attached tothe body frame 3. The carrier 24 supports the bolster holder 26 in amanner similar to that previously described and the bolster 25 issuitably secured to said bolster. 2S is a radial arm pivotedto a bracket29 carried by the body frame 3 and which extends into proximity with theaxle on which the bolster carriers 24 are nmunted. This arm is providedwith a pair of vertical Aguides Si() located at the sides of the. axleand adapted to move vertically with the arm. 3f is a saddle bloc-lisecurely fitted to the spring t) and confined between the guides o; theradial arm 2i" and provided with a shoe 32 which rests upon the bolster25. lt will bc seen that this construction provides for the movement ofthe saddle bloclrin a mannelto permit the cushioning action of thepneumatic bolster in order that shocks will not be comnumicated from theground wheels of the vehicle to the bodyof such vehicle.
